When you request an address that is not in the cache, a cache miss occurs. The system will then retrieve the data from a slower storage layer, such as main memory or disk, to fulfill the request. This process typically involves additional latency, as the data must be fetched and loaded into the cache for future access. Once the data is retrieved, it may be stored in the cache for quicker access on subsequent requests.
The request was processed with a cache hit.
The purpose of an arp request is to map an IP address to a MAC address for the link layer to transmit a packet. For example, ARP will get a request to map 1.2.3.4 to a MAC address 12:fd:23:gf .Then ARP will cache the address mapping that next time an arp request doesnt need to happen
When you ping a PC, your computer first checks its ARP (Address Resolution Protocol) cache to see if it already has the MAC address associated with the target IP address. If the MAC address is not found in the cache, your PC sends an ARP request to the local network, asking "Who has this IP address?" The device with the matching IP address responds with its MAC address, allowing your PC to store it in the ARP cache for future communications. This process enables the delivery of packets over the local network.
The memory used to hold the address of the data stored in a cache is typically referred to as the "tag" memory. Each cache line has an associated tag that identifies the specific block of main memory that the data corresponds to. When the processor checks the cache for data, it compares the requested address against the tags in the cache to determine if the data is present (cache hit) or not (cache miss).

Cache is not ON farmville itself. Cache is your temporary internet files and history as such. In some cases, Zynga might request you clear your cache to see new features. This can be done by going to (IE7,IE8) Safety --> Delete Browsing History.
It's strictly a function of speed. To read what's in cache, the processor does not need to address the buss and wait for the response. Cache memory is available instantly.
ARP is used to find a MAC (layer-2) address, if you know the IP (layer-3) address.First, a device will search its ARP cache, to see whether it already happens to have the required address. If it doesn't find the address, it will send an ARP request as a broadcast, which basically asks "Who has such-and-such an IP address?" The machine that has the requested IP address will send an ARP reply.
IP addresses are assigned by DHCP servers, not by routers. DHCP servers will cache your IP address and reassign the same IP until the cache is cleared. ----
The response from the server is: HTTP/1.1 200 OK This means that the request from the client succeeded. If the page you requested is already stored in the cache of your browser you will get: HTTP/1.1 304 Not Modified This means that the page has not been modified since it was stored in your cache.
